T1: Cooperative Near-Capacity Wireless System Design
Presented by: Lajos Hanzo, University of Southampton, UK
Time: 08:30–17:00
Room: TBA

 

Abstract
This overview introduces the principles of cooperative communication,
commencing with the introduction of the basic MIMO types of

1. Beamforming;

2. Space-time coding;

3. Spatial Division Multiplexing;

4. Spatial Division Multiple Access;

The limitations of MIMOs relying on co-located array-elements are
highlighted and it is shown, how the single-antenna-aided cooperative mobiles may circumvent these limitations by forming MIMOs having distributed elements. This concept is also referred to a Virtual Antenna Arrays (VAA). Then the corresponding amplify-forward and decode-forward protocols as well as their hybrids are studied. Channel coding has to be specifically designed for the VAAs in order to prevent avalanche-like error-propagation. Hence sophisticated three-stage-concatenated iterative channel coding schemes are proposed and it is argued that in the absence of accurate channel information at the relays the best way forward might be to use multiple-symbol differential detection. Indeed, it is rather unrealistic to expect that an altrustically relaying handset would also accurately estimate the source-relay channel for the sake of high-integrity coherent detection. EXIT-chart-aided designs are used for creating near-capacity solutions and a range of future research directions as well as open problems are stated.

Tutorial Objectives
Upon completion of this tutorial, participants will be able to:

o Decide upon the AF versus DF design benefits;

T2: LTE-Advanced Modem Design: Challenges and Perspectives
Presented by: Dongwoon Bai, Claudio R. C. M. da Silva, and Jungwon Lee
Time: 13:30–17:00
Room: TBA

 

Abstract
Following the great commercial success of LTE Release 8/9, LTE-Advanced is set to become the leading solution for 4G cellular systems across the globe. LTE-Advanced meets or exceeds the requirements set by the ITU for IMT-Advanced and offers increased peak data rate (3 Gbps in the downlink), higher spectral efficiency (30 b/s/Hz), and support to a larger number of simultaneously active subscribers. In order to meet such ambitious performance targets, LTE-Advanced relies on innovative radio-access technologies that bring new challenges to its design and implementation. In this tutorial, our main goal is to identify the main challenges in the design of signal processing algorithms and physical layer techniques for LTE-Advanced Release 10/11 mobile terminals, and to discuss possible solutions to the identified technical issues. The primary areas to be covered for Release 10 are: carrier aggregation, enhanced inter-cell interference coordination (eICIC) for heterogeneous networks (HetNets), detection of eight-layer transmission, reference signals for enhanced multi-antenna support, and hybrid automatic repeat request (HARQ) buffer management. Covering Release 11 modem design challenges, coordinated multiple point (CoMP) transmission and reception will also be discussed. For each of these topics, we present an overview of their main design challenges and discuss possible solutions.

Tutorial Objectives
To meet the spectral efficiency and peak throughput targets defined in the IMT-Advanced (4G cellular) specifications, LTE-Advanced relies on a number of advanced radio-access technologies that can still be considered as 'work-in-progress' and present interesting design and implementation challenges. These technologies include carrier aggregation, heterogeneous networks, extended multi-antenna transmission, and coordinated multiple point operation, among others.

Our objective in this tutorial is not to give a general overview of LTE/LTE-Advanced. Instead, our primary goal is to identify the main challenges in the design of signal processing algorithms and physical layer techniques for LTE-Advanced terminals and to discuss possible solutions to the identified technical issues. By shedding light on design challenges and potential research venues, we hope to promote research and the advancement of future cellular networks and, in particular, of the physical-layer of LTE-Advanced systems among IEEE members, who undoubtedly will continue playing a critical role in their evolution.

T5: Spatial Modulation for MIMO Wireless Systems
Presented by: Marco Di Renzo (CNRS) Ali Ghrayeb (Concordia Univ.) Harald Haas (Univ. Edinburgh)
Time: 08:30–12:00
Room: TBA

 

Abstract
The key challenge for future wireless communications is to make these networks energy-efficient and spectrum efficient at the same time. This results in a paradigm-shifting requirement which necessitates a clean-slate approach of wireless system design. Clearly, such approach will have to embrace the rich body of knowledge that has been created especially on Multiple-Input-Multiple-Output (MIMO) technology during the last 25 years. This motivates us to give a tutorial on an emerging wireless communications concept for 'massive' MIMO systems, which is today known under the name of Spatial Modulation (SM). SM has recently established itself as a beneficial transmission paradigm, potentially subsuming all members of the MIMO wireless system family, which exploits multiple antennas in a novel fashion. The research on SM has reached sufficient maturity to substantiate its claimed advantages compared with state-of-the-art standardized MIMO concepts, as well as its applications to other emerging wireless systems such as relay-aided, cooperative, small cell, optical wireless, and green communications. Furthermore, it has received sufficient attention to be implemented in testbeds, and holds the promise of stimulating further vigorous inter-disciplinary research in the next years. We believe that this is a timely topic and we anticipate that this tutorial will be of interest to many researchers/students/practitioners with different backgrounds.

Tutorial Objectives
Future wireless communication systems deployment, including fifth generation (5G) cellular systems, will be based on the MIMO transmission technology. Conventional MIMO schemes usually take advantage of the many antennas available at the transmitter by simultaneously transmitting multiple data streams from all of them. Furthermore, common open-loop MIMO schemes usually assume that all transmit-antennas are simultaneously active at any time instance. By properly choosing the transmission matrices, both multiplexing and transmit-diversity gains can be obtained via space-time coding. As a consequence, higher data rates and smaller error performance are obtained at the cost of: i) increasing the signal processing complexity at the receiver, which is caused by the need to counteract the interference created by simultaneously transmitting many data streams; and ii) making more stringent the synchronization requirements among the transmit-antennas.

Furthermore, more recently, with the advent of the green and sustainable information and communication era, state-of-the-art MIMO schemes are facing two additional major challenges: i) the need of multiple RF chains at the transmitter to be able to simultaneously transmit many data streams, which do not scale with Moore's law and make the transmitter very bulky; and ii) the need of independent power amplifiers for each RF chain, each one being responsible of the vast majority of the power consumed at the transmitter as well as being extremely power inefficient due to the stringent linearity requirements of state-of-the-art phase/amplitude modulations. For example, recent studies have shown that, for a fixed RF output power, the total power consumption of base stations linearly increases with the number of active RF chains.

These considerations imply that a major challenge of next-generation MIMO-enabled wireless networks is the design of multi-antenna transmission schemes with a limited number of active RF chains aiming at reducing circuitry complexity, inter-antenna synchronization requirements, inter-channel interference, signal processing complexity at the receiver, as well as at improving the energy efficiency. Fueled by these considerations, SM has recently established itself as an emerging and promising transmission concept belonging to the 'massive' MIMO wireless systems family but exploiting the multiple antennas in a novel way compared with state-of-the-art high-complexity and power-hungry classic MIMOs. This tutorial is intended to offer a comprehensive state-of-the-art survey on SM-MIMO, the critical appraisal of its beneficial application domains and their research challenges, the analysis of the related technological issues associated with the implementation of SM-MIMO, and, finally, the description of the world's first experimental activities in this research field.
